1090 - Largest Values From Labels\. Medium There is a set of `n` items. You are given two integer arrays `values` and `labels` where the value and the label of the ith element are `values[i]` and `labels[i]` respectively. You are also given two integers `numWanted` and `useLimit`. Choose a subset `s` of the `n` elements such that: * The size of the subset `s` is **less than or equal to** `numWanted`. * There are **at most** `useLimit` items with the same label in `s`. The **score** of a subset is the sum of the values in the subset. Return _the maximum **score** of a subset_ `s`. **Example 1:** **Input:** values = [5,4,3,2,1], labels = [1,1,2,2,3], numWanted = 3, useLimit = 1 **Output:** 9 **Explanation:** The subset chosen is the first, third, and fifth items. **Example 2:** **Input:** values = [5,4,3,2,1], labels = [1,3,3,3,2], numWanted = 3, useLimit = 2 **Output:** 12 **Explanation:** The subset chosen is the first, second, and third items. **Example 3:** **Input:** values = [9,8,8,7,6], labels = [0,0,0,1,1], numWanted = 3, useLimit = 1 **Output:** 16 **Explanation:** The subset chosen is the first and fourth items. **Constraints:** * `n == values.length == labels.length` * 1 <= n <= 2 * 104 * 0 <= values[i], labels[i] <= 2 * 104 * `1 <= numWanted, useLimit <= n`
